A Compact Triple Band Antenna for WLAN and WPAN Applications

The antenna covers 2.4/5 GHz WLAN and 7.4 GHz WPAN frequency bands. To obtain the triple band nature of antenna two additional rectangular slots are incorporated in ground plane. The optimized dimensions of the proposed uniplanar antenna are 19 mm x 21 mm x 1.6 mm when printed on a substrate of dielectric constant 4.4 and height 1.6 mm. The antenna exhibits good gain characteristics in operating bands. Details of the antenna design, simulation, and results are presented and discussed.
